## What is Bottle Diary?

Bottle Diary is an interactive journaling app where you record your day by chatting with an AI cat.

Tell your cat what happened today.
As you enjoy a relaxing conversation, the cat will turn your story into a thoughtfully written journal entry.

You can talk about happy moments, difficult experiences, or even the smallest parts of an ordinary day. There’s no need to worry about what to write—simply follow the conversation, and your journal entry will come together naturally.

You can keep your completed entries private or share them anonymously. Read journals shared by others, leave kind replies, and experience a quiet sense of connection—even without knowing each other’s names.

Earn coins by writing entries and reading other people’s stories. Use your coins to dress up and care for your own cat, making journaling a cuter and more enjoyable daily habit.

### 3/5 — 대화하고 일기로 나온 내용이 너무 어색해요

*2026-08-26*

제목 그대로임 이럴바엔 걍 내가 직접 정리해서 쓰고말지; 대화한 내용을 정리하거나 요약한 것도 아니고 걍 내가 보낸 내용 그대로 복사 붙여넣기 한 수준이라서 어이가 없음ㅋㅋ 지피티가 더 자연스러울 듯 ㄹㅇ

### 5/5 — 재밌어요!

*2026-07-21*

고양이가 귀엽네요 ㅋㅋ 캐릭터 더 많아졌으면 좋겠어요
